Heterojunction strategy has proven to be an effective approach for overcoming the quick photoexcited charge carrier recombination of graphitic carbon nitride (g‐C 3 N 4 ) and facilitating its photocatalytic performances. Bearing the merits of transition metal dichalcogenides (TMDs) in mind, in this work, a novel flower‐like ReS 2 coupled with layered g‐C 3 N 4 was constructed via a facile hydrothermal route. The hybrid ReS 2 /g‐C 3 N 4 catalysts create excellent photocatalytic hydrogen evolution without any additional co‐catalyst. Under visible‐light irradiation, the optimized 3 wt % ReS 2 /g‐C 3 N 4 heterojunction exhibited a hydrogen evolution rate 8 times that of pristine g‐C 3 N 4 , maintaining a stable heterojunction after multiple photocatalytic cycles. ReS 2 /g‐C 3 N 4 integrates the merits of both the configuration of a heterojunction and the formation of spatially conductive network, which effectively accelerate the transfer of photoinduced carrier. This work not only presents a marked ReS 2 /g‐C 3 N 4 heterojunction photocatalyst, but provides more possibility for expanding applications in electrocatalysis, photothermal catalysis and energy storage.
